I suppose that's one of the best ways to deal with the problem: to experience it. This simulation was of great importance. Gabi can now provide an objective opinion on the problem. She can point people at their stereotypes.
The only thing I'm curious about is how did she actually manage to fool everybody, including her parents?!

Gabi is an 80lvl troll)))

Seriously though it might be an effective means of checking the social attitude and tolerance. But anyhow it's too cruel and heartlessly towards relatives and other close ones - one can get the joke in a wrong way...
